Winyah Bay is comprised of 525,000 total acres and encompasses the lower drainage of the Black, Big Pee Dee, Little Pee Dee, Sampit, and Waccamaw rivers. This vital watershed sustains 123,000 acres of forested wetlands and 23,000 acres of tidal freshwater marshes that support the annual use of up to 40,000 migratory waterfowl, 6 federally threatened and endangered species, and numerous species of migratory songbirds. These wetlands and associated uplands are of national significance. In collaboration with the Winyah Bay Task Force, The Nature Conservancy has also protected Sandy Island, located in Winyah Bay. This 12,000-acre island is the most biologically significant tract in the area. To date, the Conservancy has helped to protect 20,340 acres in Winyah Bay, and the Task Force partners have protected more than 56,000 acres overall.
